82726240 ÷ 407 
The aim is to understand the frequency of 407 in 82726240.

On to step 1:
If we divide 8 by 407, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 407

Step 2:
The number 407 fits into 82 0 times, leaving a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 407

Let's proceed to step 3:
When dividing 827 by 407, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 13 after subtracting 814 from 827.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 407

Going ahead to step 4:
When dividing 132 by 407, we get 0 with a remainder of 132.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 132 and we're left with 132.
Fetch the next digit (6) from the dividend, attach it to 132 and continue: 1326 / 407

Advancing to step 5:
407 can be fit into 1326 3 times, resulting in a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 203.0
If we take 1221 away from 1326, we end up with 105.
Take the next digit (2) from the dividend and append it to 105, then repeat: 1052 / 407

Step 6:
The number 407 fits into 1052 2 times, leaving a remainder of 238.
The next digit of our result is 2. 
Result so far: 2032.0
Subtracting 814 from 1052 leaves us with 238.
Grab the next digit (4) from the dividend, add it to 238, then carry on: 2384 / 407

Advancing to step 7:
407 can be fit into 2384 5 times, resulting in a remainder of 349.
The next digit of our result is 5. 
Result so far: 20325.0
Deduct 2035 from 2384 and we're left with 349.
Fetch the next digit (0) from the dividend, attach it to 349 and continue: 3490 / 407

Let's proceed to step 8:
The number 407 fits into 3490 8 times, leaving a remainder of 234.
Use 8 as the next digit of our solution. 
Result so far: 203258.0
The remainder is 234 after subtracting 3256 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 9:
407 can be fit into 2340 5 times, resulting in a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 203258.5
If we take 2035 away from 2340, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 10:
The number 407 fits into 3050 7 times, leaving a remainder of 201.
Put 7 as the next digit of the answer. 
Result so far: 203258.57
If we take 2849 away from 3050, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 11:
If we divide 2010 by 407, we get 4 and a remainder of 382.
Record the quotient 4 as the next digit in the result. 
Result so far: 203258.574
Subtract 1628 from 2010 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 12:
If we divide 3820 by 407, we get 9 and a remainder of 157.
Put 9 as the next digit of the answer. 
Result so far: 203258.5749
Subtract 3663 from 3820 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 13:
407 can be fit into 1570 3 times, resulting in a remainder of 349.
The number 3 becomes the next digit in our result. 
Result so far: 203258.57493
Subtract 1221 from 1570 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 14:
407 can be fit into 3490 8 times, resulting in a remainder of 234.
Write down 8 as next digit of the result. 
Result so far: 203258.574938
If we take 3256 away from 3490, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 15:
The number 407 fits into 2340 5 times, leaving a remainder of 305.
The next digit of our result is 5. 
Result so far: 203258.5749385
If we take 2035 away from 2340, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 16:
407 can be fit into 3050 7 times, resulting in a remainder of 201.
Use 7 as the next digit of our solution. 
Result so far: 203258.57493857
The remainder is 201 after subtracting 2849 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The final result is 203258.57493857 with a remainder of 2.01e-07.
